High ground-level ozone (GLO) concentrations will adversely affect human health, vegetations as well the ecosystem. Therefore, continuous monitoring for GLO trends is a good practice to address issues related air quality based on high of GLO. The purpose this study introduce stationary and non-stationary model extreme method applied 25 selected stations in Peninsular Malaysia. maximum daily con...
In this paper we discuss the theory of adjoint sensitivity analysis and the method of 4D-Var data assimilation in the context of the Sulfur Transport Eulerian Model (STEM). The STEM atmospheric Chemical Transport Model (CTM) is used to perform adjoint sensitivity analysis and data assimilation over the State of Texas. We first demonstrate the use of adjoint sensitivity analysis for a receptor l...
An analysis is presented for both ground- and satellite-based retrievals of total column ozone and nitrogen dioxide levels from the Washington, D.C., and Baltimore, Maryland, metropolitan area during the NASA-sponsored July 2011 campaign of Deriving Information on Surface COnditions from Column and VERtically Resolved Observations Relevant to Air Quality (DISCOVER-AQ). Satellite retrievals of t...
